State transportation officials are bracing for delays on the roadways this weekend as lane closures and roadwork coincide with a busy time for shoppers and event-goers.

Parents are expected to flock to stores this weekend for back-to-school shopping to take advantage of the tax-free holidays. Plus, the Williamson County Fair is expected to attract hundreds of thousands of people.

Bridge repair work on Interstate 65 near the Rivergate Mall in Goodlettsville will force one lane to be closed through the weekend on the northbound side.

Construction crews are racing to finish work on five bridges in the area before the start of Titans football season, said Heather Jensen, a spokeswoman for the Tennessee Department of Transportation.

“We can’t stop the work that’s happening on 65 north of town,” she said. “We’re doing everything we can to minimize the impact to motorists.”

Meanwhile, construction continues on I-65 in Williamson County between State Route 840 and the Goose Creek Bypass.

“We just want to let people know that this is an active construction site,” Jensen said. “There’s plenty of signage out there, but you know how people don’t always take heed of the signs. And that causes a logjam.”

Motorists who aren’t going to the fair should try alternate routes to avoid the congestion, Jensen said.
